Yale Announces the Start of Geophysics at Guadalupe

Yale Resources Ltd. (TSX-V: YLL; Frankfurt: YAB) is pleased to announce
that the next phase of field work has started at the wholly owned
Guadalupe property, located in the heart of the Fresnillo district, on
behalf of partner Gold American Mining Inc. (OTC ? SILA, previously
Silver America Inc.).

The field program underway will include seventeen line kilometres of
geophysics (Induced Polarization and Magnetics) as well as additional
detailed sampling and mapping. This second phase of exploration is
expected to last 3 weeks.

Yale′s Mexican staff has recently acquired additional geological data
for the Guadalupe property and surrounding area. This data indicates
that additional historical workings exist within the property that have
not been visited or sampled by Yale to date. Along with the geophysics
these new areas will be a focus of this next phase of exploration.

The Guadalupe Property:

The 282.84 hectare Guadalupe Property is located approximately 4
kilometres north of the city of Fresnillo, Zacatecas State, Mexico. The
property is approximately 8 kilometres north of the Fresnillo (Proaño)
Mine, the world′s richest underground silver mine operated by Fresnillo
plc. The property is also approximately 11 kilometres northeast of the
Juanicipio Joint Venture between MAG Silver Corp. and Fresnillo plc.

The Property contains greater than 20 known workings as well as two
historic mines ?Santa Rita and San Antonio. Historic records containing
references to the Santa Rita and San Antonio mines suggest that both
mines were important and reached their height of production between 1910
and 1920 but were last in production in the 1980′s. The property is
completely surrounded by land controlled by Peñoles (either through
Fresnillo or other subsidiaries and partners).

Highlight results from the first phase exploration program were (see
news release dated May 13, 2010):

• 
  1.00 g/t Au and 946.9 g/t Ag over 1.1m
  
  
  • 
    including 1.83 g/t Au and 1,800.0 g/t Ag over 0.5 m
    
• 
  0.30 g/t Au and 622.0 g/t Ag from a mineralized dump
  
• 
  0.59 g/t Au and 330.0 g/t Ag over 0.7 m
  
• 
  5.35 g/t Au and 1,189.0 g/t Ag from a mineralized dump
  

Status of Option Agreement:

Gold American has committed to the next period of the Guadalupe option;
Yale has received US$20,000 cash as well as an additional 100,000 shares
in the Gold American.

To earn a 90% interest Gold American is required to pay Yale US $
900,000 cash ($40,000 received), spend US $ 2,000,000 on exploration
expenditures and issue 1,000,000 shares to Yale (200,000 received) in
staged payments over four years. Yale will act as the operator for the
project. The minimum work commitment before June 30, 2011 is US $
400,000 including a minimum of 2,000 metres of drilling. Should the
earn-in be completed Yale will retain a 10% participating interest in
the property as well as a 2% NSR, which can be bought out in entirety
for US $ 2,000,000.

About Yale Resources:

Yale Resources is an exploration and development company concentrating
in northwestern Mexico that is building value through project
generation. Yale has three of its seven properties optioned out to value
added partners. These agreements combine for minimum commitments of
approximately US $1,250,000 of exploration expenditures over the next 12
months. Yale continues to work on its non-optioned properties as well as
reviewing new projects with a focus on gold.

Samples from the Guadalupe property were prepared and analyzed by
Stewart Labs in their facilities in Mexico and Kamloops, respectively.
Samples generally consisted of 1-3 kg of material. Gold and silver
analyses were performed by 30 gram fire assay with an AA finish. Samples
with greater than 100 g/t silver were re-assayed using gravimetric
methods.

Ian Foreman, P.Geo., is Yale Resources′ Qualified Person, as defined by
National Instrument 43-101, for the Guadalupe property. The Guadalupe
property is an early stage project with no reported resources that
requires additional sampling and geological mapping to fully determine
the project′s potential.
